High-density polyethylene (HDPE)

High-density polyethylene (HDPE) or high-density polyethylene is actually a thermoplastic polymer. This product is produced from the monomer ethylene. In some cases, this polymer is used for HDPE pipes, in which case it is called “alkathene” or “polythene”. High-density polyethylene has high strength and is used in the production of plastic bottles, corrosion-resistant pipes, geomembranes and plastic lumber. Polyethylene is often recyclable. In this product, its resin identification code is the number “2”. In this article from the specialized site Pipe Ethylene, we want to talk about high-density polyethylene and review information in this field.

High-density polyethylene

High-density polyethylene (HDPE) is a thermoplastic polymer. This product is made from petroleum. HDPE plastic is one of the most widely used plastic materials, plastic bottles, milk bottles, shampoo bottles, bleach bottles, cutting boards and plumbing are among the most widely used of this type of plastic. HDPE plastic has high tensile strength and is also very strong in relation to its density and has very high resistance to high temperature conditions.

This type of plastic was introduced to the global market in 2007 and its volume reached more than 30 million tons.

In addition to the above cases, which are often in the food industry, high-density polyethylene can also be searched for in other cases. We will discuss some of them below:

Wood plastic composites
Plastic surgery, especially skeletal and facial reconstruction
Shoes
3D printing thread
Food and beverage containers
Advantages of high-density polyethylene:

High-density polyethylene (HDPE) sheets are of high industrial quality that are approved by the FDA, NSF and USDA. This product requires little maintenance and is also safe for a long time. One of the most important features is its special texture. In fact, the textured surface is the best reason for storing food in it.

Easily melts and molds

High-density polyethylene has heat resistance, although the main material of this product is plastic, which is actually a petroleum derivative, but it retains its inherent shape very well. The high melting point of high-density polyethylene makes it remain solid at very high temperatures. Just when it reaches its melting point, products such as detergent bottles, milk bottles, food storage containers, corrosion-resistant pipes and plastic barrels can be molded and finally produced.

Corrosion Resistance

High-density polyethylene, or HDPE, is weather-resistant and does not corrode easily, mold, or rot, making it a good choice for underground pipes used for water transportation. Since it is highly heat-resistant and does not corrode with water, it can be easily sterilized with boiling water. This feature is the most important option for food and beverage containers. Of course, HDPE can also withstand strong mineral acids and bases and does not react with them. Therefore, it is highly resistant to natural chemicals found in the soil. High-density polyethylene is resistant to most chemicals such as water, solvents, acids, detergents, and cleaning fluids and does not allow penetration.

High-density polyethylene strength to high density ratio

HDPE density can vary from 0.93 to 0.97 grams. The density of HDPE is only slightly higher than that of LDPE (low-density polyethylene), however, when viewed under a microscope, the linear structure of HDPE shows little branching, which makes it have stronger intermolecular forces than LDPE. Considering this feature, as a simple example, it can be said that a 60-gram HDPE container can withstand four kilograms of weight.

In today’s world, due to the increase in population and the subsequent excessive consumption of plastic and its inability to recycle and decompose, one of the concerns of experts is to use materials that can be recycled sooner. HDPE plastic is easily recyclable. The use of this material greatly reduces the need to use plastic. High-density polyethylene is a suitable, cost-effective and environmentally friendly material.

The need to use high-density polyethylene:

This product allows all types of manufacturers to use this material as the most suitable carrier. High-density polyethylene is a suitable material for manufacturers to transport their products due to its high strength, resistance to heat and corrosion, and affordable price.

Since wood in its natural state is porous and traces of food may remain in its grooves, high-density polyethylene can be a suitable and alternative product and is much more suitable for maintaining food hygiene and preserving it.

Final words:

By studying this article, we found that high-density polyethylene is a suitable and environmentally friendly material that is very useful for uses such as the food industry. This material replaces many materials such as wood. Because the possibility of bacterial growth and food spoilage is less in it. On the other hand, the lack of corrosion and heat resistance of this material also increases the importance of its use in industries.
